Abstract (en)
[origin: US2017275988A1] Methods and systems for optimizing the placement of perforation clusters in horizontal wells for completion include conveying a carrier through a borehole into a horizontal section of the borehole; obtaining acoustic data using one or more acoustic sensors; defining a first location for each of a plurality of perforation clusters based on a geometrical distribution; identifying a minimum horizontal stress (Shmin) for each first location based on the acoustic data; calculating a differential net pressure for the first locations based on the minimum horizontal stress (Shmin) for each first location; adjusting the location of each of the plurality of perforation clusters to a respective second location such that the differential net pressure of the second locations is less than the differential net pressure of the first locations; and deploying a plurality of perforation clusters to the second locations such that fracturing of a formation at the second locations is achieved.
